New Developments in Manufacture and Use of Liquid Fertilisers
Achorn, Frank P.
This document provides an overview of the developments in the manufacture and use of liquid fertilizers over the past five years. While using liquid fertilizers on a large scale is relatively new, spanning only about 20 years, it has proven to be an area ripe with opportunities for innovation. The paper explores the historical context of liquid fertilizer use and highlights significant advancements and trends in the field. It discusses the objectives of liquid fertilizer production, such as cost efficiency, high nutrient concentration, product quality, low pollutant emission, and uniform application. The challenges and advantages associated with liquid fertilizers are examined, with a focus on nutrient concentration and the use of polyphosphates. The paper summarizes recent polyphosphate chemistry and hydrolysis research, offering insights into improving liquid fertilizer production and addressing associated issues.
